To all whom zit may concern.-

Be it known that I, WILLIAM J EFFERYS, a citizen of the United States, residing in the township of East Orange, in the county of Essex and State of New Jersey, have invented. certain new and useful Improvements in Sewer or Drain Pipes or Conduits for t'Vaterways; and I do hereby declare that the followingis a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

The object of my invention is to provide a sewer or drain pipe or conduit of a flexible or yielding nature, so that it will easily conform to lines of projection to be used for conducting its contents through marshy soil or I attain this object by the mechanism illustrated in the accompan ying drawings.

Figure 1 is a longitudinal section of the pipe or conduit, showing layers of woven or formed metal A a, alternating with sheets or layers formed of paper or other pulpous ma,- terial B b, coated with a water-resisting sub- Serial No. 685,806. No model.)

stance or solution, which being pressed to gether form a compact and cohesive and flexible mass shaped in any form for conveying liquid matter. Fig. 2 is a vertical crosssection of the same.

By the application of this method the pipe or conduit is made without joints, and thus is free from leakage and, being flexible or yielding, is easily bent to arequired direction, is not liable to decay or fracture, and therefore is adapted to the purpose designed. v

Having fully described my invention, what I claim, and desire to secure by Letters Pat= ent, is

The combination of layers of woven or formed metal, coatings or layers of oily or "iscous matter, and sheets or layers formed of pulpous material, alternating in regular or irregular order, forming a compact and cohesive mass, shaped for conveying liquid matter, substantially as described.

WILLIAM JEFFERYS.
